Detailed Description of Preferred Embodiments
The invention described is a mixing and recirculation circuit consisting of a processing volume and more than one storage and feeding container with a self adjusting feed and drain system connecting the processing volume and the containers providing equal liquid levels in the storage and feeding containers The present invention is a simple self controlled mixing system integrated into a process, based on recirculation of a liquid, in a loop, with the liquid gradually changing, as parts of the liquid components are consumed during processing. The liquid is re-circulated between a process volume and a number of loose containers acting as storage tanks in which the liquid is automatically equally distributed without control. This invention is differing from other systems in the fact that other known mixing systems either rely on simple mechanical mixing
with rotating parts in one pot, or as for systems using static mixers relying on complicated loop systems, tied to specific processes, or as in continuous mixing mainly performs in complicated equipments using a high degree of control. The invention consists of a number of parts, being a processing volume with a liquid contained, that is taking part in a process gradually removing components from said liquid thereby changing chemical and physical characteristics of said liquid, a number of removable storage containers, a unit (Fig. 1 [2]) for simultaneously pumping liquid from more than one selected member of container, that is a pump with a branched fluid conductor with a number of branches equal to the number of containers, and a part (Fig. 1 [3]) for bringing liquid from the processing volume to said selected containers, a branched liquid conductor having the same number of branches as the pump activated one. The branches are pair wise selected from the fluid conductors and mounted with the openings of the branches below a lowest selected level of liquid in each of the selected containers together with' a gas duct to secure equal pressure in all selected containers. The air duct (Fig. 1 [1] ) is placed above the highest level of liquid in the selected containers . In order to enable equal pressure in the air duct and in the selected containers, the containers are closed so that a confined space is formed by the selected containers and the air duct.
The whole loop is therefore acting as a mixer, in which the processed liquid is mixed with the less processed liquid in the storage tanks, at the same time, as a part of the mixture is pumped from both containers into the process volume, continuously replacing and mixing with the processed liquid. In its simplest form
the number of containers are two. The excess liquid from the processing is running back into the containers of mixed liquid. Distribution of a liquid in more containers is most often done by filling the containers in turn or only filling these to the half. The self controlled process of the liquid flow in the loop that involves distribution of liquid on more than one container is dependent on the way the re-circulation takes place, as unstable refilling of the storage containers, when starting with filled containers inevitably results in overfilling one of the containers. This invention makes use of a self-regulating technique where the distribution between two or more containers that are emptied and filled, at the same rate, to and from the same reservoir placed above the containers will be regulated by the flow resistance in the leads to and from the containers. The flow resistance of the pumping part in a geometrically symmetric flow circuit with the same type of connection and with a suction pipe to each of two containers of the same type, will only differ among the leads from the containers due to different level of liquid over the mouth of the suction pipes in the containers . The liquid flow will be highest in the suction pipe with the highest level of liquid as less work is needed against the force of gravity to pump from this pipe. The same regulation is taking place with the liquid running back through a similar pipe system, as a high liquid level means higher pressure in the pipe counter acting the liquid flow.
